“When students confront complex problems, they often feel confused. A teacher’s natural impulse is to rescue them as quickly as possible so they don’t feel lost or incompetent.

One student put it eloquently: “I need time for my confusion.” Confusion can be a cue that there’s new territory to be explored or a fresh puzzle to be solved.”
